Definitions
- the invention relates to a rotary windrower according to the preamble of patent claim 1.
- DE-OS 196 03 400 is an executed as two-rotor rake agricultural machine disclosed whose staggered arranged in the direction of travel work organs are hydraulically arranged to extend in the direction of travel axes between a lower working and an upper transport position pivotally mounted on a machine frame.
- a Hubzylinder horrung is disclosed, which triggers a single time triggering of the lifting of the front in the direction of travel working body a time-delayed lifting of the downstream work organ.
- the EP 0 494 516 A1 describes a control system for coordinating the work of first and second with respect to the intended direction of travel of a tractor carrier vehicles spaced apart devices, wherein a device for compensating the device spacing is proceeding to the coordination of the device work depending on the distances between the Adjust devices relative to the intended direction of travel of the tractor.
- This control system refers to at least two zueinader spaced devices and it is also technologically very complex designed.
- the invention is therefore based on the object to make a control for a rotary windrower according to the preamble of claim 1 so that the triggering of the carrier vehicle pivoting or the front in the direction of travel working bodies in response to the distance traveled on the basis of counts in conjunction with a bus system of the rotary rake an automatic pivoting of the or the downstream work organs triggers.
- the object is achieved by a control for a rotary windrower with the characterizing features of claim 1.
- a measuring and control unit between the rotary windrower and the carrier vehicle, in addition to the input signal generated by the carrier vehicle for pivoting the front or in the direction of travel working bodies automatically by comparing a generated actuating signal with a presettable threshold value, a time-shifted further output signal for pivoting or the subordinate working bodies are generated. In this way, it is ensured that the downstream working member is always raised before the Randschwad and is lowered again after passing Randschwad.
- control signal can be generated by a sensor arrangement on at least one impeller of the rotary rake.
- the sensor arrangement may comprise an inductive sensor which generates during the rotation of the corresponding impeller counting pulses, which are further processed in the measuring and control device to the control signal.
- a stepless change of the threshold value of the measuring and control device is provided, so that the measuring and control device can be universally executed and by changing the threshold value in a simple manner to the geometric conditions of the respective rotary rake adaptable.
- the measuring and control device can be advantageously supplemented by a timer, which generates the control signal regardless of the intended sensor systems after an adjustable time interval.
- FIG. 1 shows an executed as a four-rotor rake agricultural machine 1, designed as rake 2 and staggered in the direction FR arranged front and rear work organs are adapted to side frames 3, which are arranged to run in the direction of travel FR axes 4 pivotally mounted on a main frame 5, via a Wheels 6 supporting chassis 7 is supported on the ground and is adapted to its front in the direction of travel FR end to a carrier vehicle 8.
- the pivoting of the rotary rake 1 about the axes 4 takes place in a known per se and therefore not explained in more detail way by means of hydraulic lifting cylinders 9, which are pivotally mounted at one end to the main frame 5 and the other end also pivotally mounted on the respective side frame 3.
- the carrier vehicle 8 has at least one control unit 10 for the electrical and hydraulic control of the agricultural work machine designed as a four-rotor rake 1 and adapted to the carrier vehicle 8.
- the four-rotor rake 1 advantageously accommodates the measuring and control device 11 according to the invention advantageously on the carrier vehicle-side end of the main frame 5.
- FIG. 2 the control according to the invention of an agricultural machine designed as a four-rotor rake 1 is described in detail on the basis of the assemblies essential to the invention.
- the control unit 10 of the carrier vehicle 8 is connected via an electrical and / or hydraulic line system 12 with the measuring and control device 11 of the four-rotor rake 1 for transmitting the input signal X1 generated in the control unit 10.
- the measuring and control device 11 has at least two outputs 13, 14 which are connected to the known per se and therefore not shown, the lifting cylinder 9 of the rotary rake 2 enclosing hydraulic circuit 15.
- the lifting cylinders 9 are designed in the simplest case as a single-acting cylinder, so that their pressurization leads to retraction of the piston rod 16 in the cylinder 17 and thus to a raising of the rotary rake 1. Conversely, when the lifting cylinder 9 is depressurized, the piston rod 16 is pulled out of the piston 17 by the gravitational force of the respective rotary rake 2 and the rotary rake 2 pivots back into the working position.
- At least one impeller 6 of the four-rotor rake 1 is equipped with a sensor 19, which supplies in the simplest case on inductive basis as output signal W1 counts, which are offset in the measuring and control device 11 as a function of the wheel geometry to control signal W.
- the measuring and control device 11 takes the time and the count pulses W1 of the sensor 19 via line 20 and generates a path and / or speed-dependent control value W, which with a at the measuring and Control unit 11 via a threshold value switch 21 preset threshold S is compared.
- the threshold value S is based on the seen in the direction of travel FR distance between the front and rear rotary rake 2 to each other, which is constant for the disclosed four-rotor rake 1 and for the Use of the measuring and control device 11 can be reset to another generic agricultural machine according to the local geometric conditions at the threshold 21.
- the measuring and control device 11 is programmed so that the control signal W generated by them reflects the distance traveled by the four-rotor rake 1 since the beginning of raising the front in the direction of travel FR rotary rake 2. If the control signal W reaches the size of the distance between the front and rear rotary rakes 2, namely the threshold value S, the measuring and control unit 11 generates an output signal Y2, which then leads to the automatic lifting of the rear rotary rake 2. In this way, it is ensured that the rear rotary rake 2 in the direction of travel FR are always lifted automatically before the transverse edge swath 18, so that a repeated picking up of the edge swath 18 by the rear rotary rake 2 is avoided.
- the sensor 19 can, as in FIG. 2 indicated by dashed lines also be arranged on this impeller to fulfill the function described.
- At least one impeller 23 of the carrier vehicle 8 may be equipped with an inductive sensor 24 whose counting pulses W1 is transmitted via line system 25 to the control unit 10 of the carrier vehicle 8 and converted from there by means of agricultural bus system 26 in control signal W and is transferred together with input signal X1 to the measuring control unit 11.
- the arrangement of the sensor 19 and the pipe system 20 can be omitted on the agricultural machine 1.
- the data transmission between these functional modules 10, 11, 19, 24 also wirelessly by means of radio waves 28 done.
- the measuring and control device 11 additionally have a timer 29 whose time constant Z can be set so that the Raising and lowering of the rotary rake 2 even in case of failure of the control signal W generating systems 19, 24, 27, 28 is still sufficiently timely that a recording of the edge swath 18 by the working members 2 is largely avoided.
- the inductive sensors 19, 24 described in the exemplary embodiments may also be replaced by capacitive sensors or sensors operating according to the Doppler effect which are known per se and are not explained in more detail.
